Well, the use-case I have in mind is the same I keep repeating on the
Boost mailing list, as well as on the Boost.Build list, with respect to
all Boost libraries:

Improve the build system such that any Boost library can be built not
in-tree with the entire Boost superproject checked out, but only with in
its own stand-alone repo, where any references to prerequisite Boost
libraries are met from externally installed Boost libraries. (On Linux
distributions at least, I can just install individual Boost libraries,
typically into /usr/include and /usr/lib[64], so it would be great if I
could build Boost.GIL (say) using that.

I understand that Boost.Build currently doesn't support that, but I have
managed to do exactly that with Boost.Python, using faber
(, and I have indeed started work
on doing the same with Boost.GIL (see for example
